However, I get the same problem after adding the DRI section in the xorg.conf file : As root, all works fine, even at 1024x768 resolution, As a normal user, the virtual screen is much smaller than the global screen, and no menu is available. Must kill the X server. It seems this is a permissions problem in at least one of my X files, but I've no idea where to search. There is no error in the Xorg.0.log file. Thank you very much for your help. Best regards. Jean Francois Ortolo
